This will be the second child for Alfonso and Angela, who got married in October 2012. Their first child, Alfonso Lincoln Ribeiro, Jr. was born two weeks after the couple wed.
Alfonso also has a 12-year-old daughter named Sienna from his first marriage to actress Robin Stapler.
One reason Alfonso and Witney are one of the most popular couples on DWTS is because of his fun-loving style and his revival of The Carlton.
